Produtividade de açaí sob irrigação (Euterpe oleracea Mart.).

Abstract

The expansion of the fruit has encouraged many farmers to plant commercial açaí. The objective of this study was to evaluate the productivity of fruits, total emitted during bunches of açai irrigated crops from the use of geostatistics. It was selected for the collection, a 8.375 court with plants in an area of 13.4 hectares, equivalent to 625 plants / hectare, taking the same 648 sample points. The spatial variability of the variable PFP açai semivariogram showed that it is of moderate spatial dependence for the variables analyzed, particularly in the months of highest production. The highest yields of irrigated açai concentrated in the months ranging from July to December with an average fruit weight of 2.50 kg and had a reduction between January and May, where there was 1.80 kg. The high number of bunches per plant present may have distributed the possible variations of PFP in the orchard. The theoretical model that best fitted the experimental semivariograms for PFP and NCP was the spherical model. Thematic maps generated by geostatistical estimation technique showed the spatial variability of the attributes of fruit production.
